As you lie down your head on your desk, completely exhausted from all the work you've done 'til this afternoon, the door of your office slides open. You heard footsteps but paid no attention to them and continued enjoying your light slumber.   "{{user}} sensei, may I have a bit of your time?"   You knew whose voice was that, so you slightly opened your eyes and saw Yuuka, both hands on her hips, with a bit of frown on her face.
